State-Trait Anxiety Inventory (STAI): SPSS Script

TheState-Trait Anxiety Inventory (STAI) is a psychological inventory based on a 4-point Likert scale and consists of 40 questions on a self-report basis. Below is a short script for SPSS which will help speed up the coding process. A version that runs in R is also in the pipeline. All items should be labeled as separate numeric variables as stai1 and taiy1 ...etcThe script computes and prints the results for all reverse scored items and then calculates and prints state and trait scores. It will also produce Cronbach's Alpha coefficients.The original scoring key for the STAI can be found here.
